FIG. 1 is a schematic perspective view illustrating an optical memberdriving mechanism 12-101 in accordance with an embodiment of the presentdisclosure. It should be noted that, in this embodiment, the opticalmember driving mechanism 12-101 may be, for example, disposed in theelectronic devices with camera function for driving an optical member(not shown), and can perform an autofocus (AF) and/or optical imagestabilization (OIS) function.

As shown in FIG. 1, the optical member driving mechanism 12-101 has acentral axis 12-C that is substantially parallel to the Z axis. Theoptical member has an optical axis 12-O that is substantially parallelto the X axis. In other words, in the present embodiment, the centralaxis 12-C is substantially perpendicular to the optical axis 12-O. Theoptical member driving mechanism 12-101 includes a housing 12-110 whichhas a top surface 12-111, a first side surface 12-112 and a second sidesurface 12-113 (as shown in FIG. 3) that is opposite to the first sidesurface 1012. The top surface 12-111 extends in a direction that isparallel to the optical axis 12-O (i.e. the X-Y plane). The first sidesurface 12-112 and the second side surface 12-113 extend from edges ofthe top surface 12-111 in a direction (the Z axis) that is perpendicularto the optical axis 12-O. In other words, in the present embodiment, thefirst side surface 12-112 and the second side surface 12-113 aresubstantially parallel to each other. In some embodiments, the firstside surface 12-112 and the second side surface 12-113 extend from theedges of the top surface 12-111 in a direction that is not parallel tothe optical axis O.

In addition, the housing 12-110 has a rectangular first opening 12-115that is located on the first side surface 12-112, and the optical axis12-O may pass through the first opening 12-115. The light may passthrough the optical member (not shown) which is disposed in the housing12-110. After the light passes through the above optical member, it willtravel to an optical member 12-S that is disposed outside of the housing12-110. That is, the optical member 12-S corresponds to the firstopening 12-115 of the housing 12-110. For example, the optical member12-S is an image sensor, and thereby an image may be generated on theabove electronic devices. It should be appreciated that any suitableelement (not shown) may be connected between the housing 12-110 and theoptical member 12-S in order to maintain the stability of the opticalmember 12-S for generating an image. In the present embodiment, whenviewed along the optical axis 12-O (namely, the direction in which thefirst optical member and the second optical member are arranged), theoptical member 12-S and the optical member which is located inside thehousing 12-110 at least partially overlap. In addition, when viewed in adirection (e.g. the central axis 12-C) that is perpendicular to opticalaxis 12-O, the optical member 12-S and the optical member which islocated inside the housing 12-110 do not overlap.

FIG. 2 is an exploded view illustrating the optical member drivingmechanism 12-101 shown in FIG. 1. In the present embodiment, the housing12-110 of the optical member driving mechanism 12-101 has a substantialrectangular structure. The optical member driving mechanism 12-101mainly includes a fixed portion 12-F (e.g. a first portion), a movableportion 12-M (e.g. a second portion), a plurality of first elasticmembers 12-160, a plurality of second elastic members 12-161, a firstelectromagnetic driving assembly 12-140 and a second electromagneticdriving assembly 12-145. The fixed portion 12-F includes a housing12-110, a base 12-120, a frame 12-150, and a circuit component 12-170.

The housing 12-110 is disposed on the base 12-120, and protect theelements disposed inside the optical member driving mechanism 12-101. Insome embodiments, the housing 12-110 is made of metal or anothermaterial with sufficient hardness to provide good protection. The frame12-150 is disposed in and affixed to the housing 12-110. The circuitcomponent 12-170 is disposed on the base 12-120 for transmittingelectric signals, performing the autofocus (AF) and/or optical imagestabilization (OIS) function. For example, the optical member drivingmechanism 12-101 may control the position of the optical member based onthe aforementioned electric signals so as to form an image. In thepresent embodiment, a metallic member 12-121 is disposed in the base byinsert molding, and thereby the structural strength of the base 12-120may be enhanced.

The movable portion 12-M is movable relative to the fixed portion 12-F.The movable portion M mainly includes a carrier 12-130 which carries anoptical member. As shown in FIG. 2, the carrier 12-130 is movablyconnected to the housing 12-110 and the base 12-120. The first elasticmembers 12-160 are disposed on the carrier 12-130. The second elasticmembers 12-161 extend in a vertical direction (the Z axis), and areconnected to the first elastic members 12-160 and the base 12-120. As aresult, the carrier 12-130 may be connected to the base 12-120 via thefirst elastic members 12-160 and the second elastic members 12-161. Forexample, the first elastic members 12-160 and the second elastic members12-161 are made of metal or another suitable elastic material.

The first electromagnetic driving assembly 12-140 includes firstmagnetic members 12-141 and first coils 12-142. The first magneticmembers 12-141 may be disposed on the frame 12-150, and thecorresponding first coils 12-142 are disposed on the carrier 12-130.When current is applied to the first coils 12-142, an electromagneticdriving force may be generated by the first coils 12-142 and the firstmagnetic members 12-141 (i.e. the first electromagnetic driving assembly12-140) to drive the carrier 12-130 and the optical member carriedtherein to move along a horizontal direction (the X-Y plane) relative tothe base 12-120, performing the autofocus (AF) and/or optical imagestabilization (OIS) function.

In addition, the second electromagnetic driving assembly 12-145 includessecond magnetic members 12-146 and second coils 12-147. The secondmagnetic members 12-146 may be disposed on the carrier 12-130, and thecorresponding second coils 12-147 are disposed on the base 12-120. Forexample, the second coils 12-147 may be flat-plate coils such that thedifficulty and the required time for assembly may be reduced. When acurrent is applied to the second coils 12-147, an electromagneticdriving force may be generated by the second electromagnetic drivingassembly 12-145 to drive the carrier 12-130 and the optical membercarried therein to move along the optical axis O (the X axis) relativeto the base 12-120, performing the autofocus (AF) function. The carrier12-130 may be movably suspended between the frame 12-150 and the base12-120 by the electromagnetic driving force of the first electromagneticdriving assembly 12-140, the second electromagnetic driving assembly12-145 and the force exerted by the first elastic members 12-160, thesecond elastic members 12-161. Furthermore, a magnetic permeable plate12-P is disposed on the second magnetic members 12-146 for concentratingthe magnetic field of the second magnetic members 12-146 so that theefficiency of the second electromagnetic driving assembly 12-145 may beimproved. In some embodiments, the magnetic permeable plate 12-P may bemade of metal or another material with sufficient magnetic permeability.

The sensing assembly 12-180 includes a sensor 12-181, a reference member12-182 and an integrated circuit (IC) component 12-183. In the presentembodiment, the sensor 12-181 and the integrated circuit component12-183 are disposed on the base 12-120, and the reference member 12-182is disposed in the carrier 12-130. A plurality of reference members12-182 may be disposed. For example, the reference member 12-182 is amagnetic member, the sensor 12-181 may detect the change of the magneticfield of the reference member 12-182, and the position of the carrier12-130 (and the optical member) may be determined by the integratedcircuit component 12-183. In some embodiments, the sensor 12-181 or thereference member 12-182 is disposed on the fixed portion 12-F, and theother of the sensor 12-181 or the reference member 12-182 is disposed onthe movable portion 12-M.

FIG. 3 is a cross-sectional view illustrating along line B-B shown inFIG. 1. As shown in FIG. 3, the housing 12-110 has a second opening12-116, and the optical axis 12-O may pass through the second opening12-116. In the present embodiment, the optical member driving mechanism12-101 has an incident end and an outlet end, wherein the incident endcorresponds to the second opening 12-116, and the outlet end correspondsto the first opening 12-115. In the present embodiment, the light mayenter the optical member from the incident end (i.e. the second opening12-116) along the optical axis 12-O, and exit the optical member fromthe outlet end (i.e. the first opening 12-115). In the presentembodiment, the frame 12-150 is disposed between the carrier 12-130 andthe housing 12-110. When viewed in a direction (the X axis) that isparallel to the optical axis 12-O, the frame 12-150 and the carrier12-130 at least partially overlap.

In addition, the base 12-120 further has a barrier 12-122 that isdisposed to protrude towards the top surface 12-111. The barrier 12-122may have a fillet structure, and when viewed along the optical axis 12-Ofrom the first opening 12-115, the fillet structure is formed on theedge of the first opening 12-115. The optical member driving mechanism12-101 further includes a matrix structure 12-190 that is disposed onthe barrier 12-122 (such as disposed on the fillet structure of thebarrier 12-122). The matrix structure 12-190 is disposed between theoptical member 12-S and the optical member which is carried by thecarrier 12-130. For example, a first light L1 (e.g. the desired light toform an image) entering the optical member driving mechanism 12-101 maytravel along the optical axis 12-O, reach the optical member 12-S andform an image after passing through the optical member which is carriedby the carrier 12-130. Furthermore, a second light L2 (such as the noiseto be removed) may travel along a direction that is not parallel to theoptical axis 12-O, and be reflected by the matrix structure 12-190 afterpassing through the optical member which is carried by the carrier12-130, remaining inside the housing 12-110. By means of the arrangementof the matrix structure 12-190, the possibility that the second light L2reaches the optical member 12-S may be effectively reduced, thereforepreserving the image quality.

As shown in FIG. 3, the extending direction of the matrix structure12-190 is not parallel and not perpendicular to the traveling direction(i.e. the optical axis 12-O) of the first light L1. It should beappreciated that those skilled in the art may adjust the extendingdirection of the matrix structure 12-190 in response to the travelingdirection of the second light L2, and it will not be repeated in thefollowing paragraphs. In the present embodiment, when viewed along theoptical axis 12-O, the matrix structure 12-190 and the first opening12-115 at least partially overlap.

FIG. 4 is an enlarged perspective view illustrating the optical memberdriving mechanism 12-101 shown in FIG. 1 from the outlet end. As shownin FIG. 4, when viewed in a direction (the X axis) that is parallel tothe optical axis 12-O, the barrier 12-122 and a lengthwise side 12-117of the first opening 12-115 at least partially overlap, and a gap isformed between the barrier 12-122 and a widthwise side 12-118 of thefirst opening 12-115. In other words, when viewed in the same directionas above, the barrier 12-122 and the widthwise side 12-118 of the firstopening 12-115 do not overlap. In addition, the frame 12-150 has alight-shielding structure 12-151 that is disposed to protrude towardsthe base 12-120. When viewed in the direction (the X axis) that isparallel to the optical axis O, the light-shielding structure 12-151 andthe lengthwise side 12-117 of the first opening 12-115 also at leastpartially overlap. Similarly, a gap is formed between thelight-shielding structure 12-151 and the widthwise side 12-118 of thefirst opening 12-115. In other words, when viewed in the same directionas above, the light-shielding structure 12-151 and the widthwise side12-118 of the first opening 12-115 do not overlap.

In some embodiments, jagged structures 12-123, 12-152 may be formed onthe barrier 12-122 and/or the light-shielding structure 12-151 by alaser engraving process. In some other embodiments, any other regular orirregular structure may be formed on the barrier 12-122 and/or thelight-shielding structure 12-151 so as to reduce the possibility thatthe noise reflected in the optical member driving mechanism 12-101enters the image sensor, enhancing the image quality. It should be notedthat although the barrier 12-122 and the light-shielding structure12-151 are both disposed in the present embodiment, it merely serves asan example. Those skilled in the art may determine whether the barrier12-122 and/or the light-shielding structure 12-151 are disposed, oradjust the position of the barrier 12-122 and/or the light-shieldingstructure 12-151 as required.

FIG. 5 is an enlarged perspective view illustrating the optical memberdriving mechanism in accordance with another embodiment of the presentdisclosure. In the present embodiment, the jagged structure 12-123includes multiple tapered structure, and has a plurality of peaks12-124. The jagged structure 12-152 also has a plurality of peaks12-153. As shown in FIG. 5, When viewed in the direction (the X axis)that is parallel to the optical axis 12-O, the peaks 12-124, 12-153 maybe exposed from the first opening 12-115. In some embodiments, thedistance between the lengthwise side 12-117 of the first opening 12-115and the peaks 12-124, 12-153 is equal to or longer than 0.25 mm, andthereby the noise may be effectively blocked, preventing the noise fromentering the image sensor. In addition, the matrix structure 12-190 maybe disposed on the jagged structure 12-123 and/or the jagged structure12-152. As a result, the possibility that the noise (e.g. the secondlight L2 shown in FIG. 3) reaches the optical member 12-S may be furtherreduced, therefore preserving the image quality.

FIG. 6 is an enlarged perspective view illustrating the optical memberdriving mechanism in accordance with another embodiment of the presentdisclosure. As shown in FIG. 6, when viewed in the direction (the Xaxis) that is parallel to the optical axis 12-O, the peaks 12-124,12-153 may not be exposed from the first opening 12-115. Namely, thepeaks 12-124, 12-153 may overlap with the housing 12-110. In someembodiments, the distance between the lengthwise side 12-117 of thefirst opening 12-115 and the peaks 12-124, 12-153 is equal to or longerthan 0.1 mm, and thereby the noise entering the image sensor may beeffectively reduced. In addition, the matrix structure 12-190 may bedisposed on the jagged structure 12-123 and/or the jagged structure12-152 (as shown in FIG. 5). As a result, the possibility that the noisereaches the optical member 12-S may be further reduced, thereforepreserving the image quality.

FIG. 7 is an enlarged perspective view illustrating the optical memberdriving mechanism in accordance with another embodiment of the presentdisclosure. In the present embodiment, the barrier 12-122 has an uppersurface 12-125 and a cutting surface 12-126 that intersects with theupper surface 12-125. A tapered structure is formed by the upper surface12-125 and the cutting surface 12-126. The upper surface 12-125 isupwardly inclined, namely facing the carrier 12-130 and the top surface12-111. The cutting surface 12-126 is substantially perpendicular to theoptical axis 12-O, facing the first side surface 12-112. In someembodiments, a fillet between the upper surface 12-125 and the cuttingsurface 12-126 is not greater than 0.05 mm. Similarly, thelight-shielding structure 12-151 has a lower surface (not shown) and acutting surface that intersects with the lower surface. In someembodiments, a fillet between the lower surface and the cutting surfaceis not greater than 0.05 mm. In addition, the matrix structure 12-190may be disposed on the upper surface 12-125 of the barrier 12-125 and/oron the lower surface of the light-shielding structure 12-151. As aresult, the possibility that the noise reaches the optical member 12-Smay be further reduced, therefore preserving the image quality.

It should be understood that multiple embodiments for arranging thematrix structure 12-190 are provided as above, but these embodimentsmerely serve as examples without limiting the scope of the presentdisclosure. Those skilled in the art may arrange the matrix structure12-190 on the fixed portion 12-F (including the housing 12-110, the base12-120, the frame 12-150 and/or the circuit component 12-170) and/or themovable portion 12-M. In addition, although in the embodiments of thepresent disclosure, the matrix structure 12-190 is disposed as planar,however in some embodiments the matrix structure 12-190 may be disposedas curved (i.e. having a curvature). In some embodiments, the matrixstructure 12-190 may be disposed on an element or portion that is madeof metal.

FIG. 8 is a schematic view illustrating the matrix structure 12-190 inaccordance with an embodiment of the present disclosure. As shown inFIG. 8, the matrix structure 12-190 is multi-layered and includes ametallic layer 12-191, an insulating layer 12-192 and a protrudingportion 12-193. The metallic layer 12-191 is the bottommost layer of thematrix structure 12-190. For example, the material of the metallic layer12-191 includes gold (Au), silver (Ag), aluminum (Al), any othersuitable metallic material or a combination thereof. The insulatinglayer 12-192 is formed on the metallic layer 12-191. For example, thematerial of the insulating layer 12-192 includes magnesium fluoride(MgF₂), silicon dioxide (SiO₂), any other suitable insulating materialor a combination thereof. The protruding portion 12-193 is formed on theinsulating layer 12-192, wherein the area of the protruding portion12-193 on the horizontal plane (the X-Y plane) may be smaller than thearea of the insulating layer 12-192 on the horizontal plane. That is,when viewed in a vertical direction, the insulating layer 12-192 may beexposed from the protruding portion 12-193. For example, the material ofthe protruding portion 12-193 includes gold (Au), silver (Ag), aluminum(Al), any other suitable metallic material or a combination thereof. Insome embodiments, the metallic layer 12-191 and the protruding portion12-193 may be formed of the same material. In some other embodiments,the metallic layer 12-191 and the protruding portion 12-193 may beformed of different materials.

FIG. 9 is a perspective view illustrating the matrix structure 12-190 inaccordance with an embodiment of the present disclosure. As shown inFIG. 9, the matrix structure 12-190 has a plurality of protrudingportions 12-193 with different sizes. The protruding portions 12-193 areformed on the insulating layer 12-192. By means of arranging theprotruding portions 12-193 in a particular manner, the surface plasmonresonance (SPR) generated by the matrix structure 12-190 may be tuned,such that the direction of the light reflected by the matrix structure12-190 may be controlled. As a result, the possibility that the noisereaches the optical member 12-S may be further reduced, thereforepreserving the image quality. It should be understood that thearrangement (such as the sizes or arrangement of each of the protrudingportions 12-193) of the matrix structure 12-190 may be adjusted inresponse to light (e.g. visible light, infrared light, etc.) withcertain range of wavelength. Therefore, the function to avoid the noiseworsening the image quality may be achieved.

As set forth above, the embodiments of the present disclosure provide anoptical member driving mechanism including a matrix structure thatcorresponds to the noise. By means of the arrangement of the matrixstructure, the possibility that the noise reaches the optical member maybe further reduced, therefore preserving the image quality. As a result,the optical member driving mechanism may be simplified and miniaturized.In addition, the matrix structure may be disposed with otheranti-refection structures (such as barriers), further enhancing thepreservation for high-quality image.
